Critical aspects of measurements when making a cantenna waveguide for radio astronomy. Extracts from SARA & BAA Radio Astronomy Group Mailing Lists 19/11/2025.
From Marcus D. Leech: Probe placement with regards to the distance from the back-short, probe length, and positioning of the waveguide at the proper dish<>feed spacing. That is, if you…
What is benefit of upgrading from 1m dish to 2.4m dish for hydrogen line?
This analysis is for a friend who has made this upgrade. The largest diameter dish we are currently using at LRO is 150cm dish made of 6 petals – soon…
How to change a normal Python‐level GNU Radio variable after the flowgraph has started
You can’t usually change a normal Python‐level GNU Radio variable after the flowgraph has started, but there are workarounds = you can make a variable externally adjustable while the script…
